Install

Add this line to your pubspec.yaml.

dependencies:
  typewritertext: ^3.0.9

Usage

First, import the typewriter package.

import 'package:typewritertext/typewritertext.dart';

And use it like this

TypeWriter.text(
  'lorem ipsum dolot sit amet ...',
  duration: const Duration(milliseconds: 50),
);

And for the builder, you need to initiate a controller like this one.

final controller = TypeWriterController(text: 'Hello World',
  duration: const Duration(milliseconds: 50),
);

// also if you want the typewriter to not only changing
// the character but also words, you can use this controller.

final valueController = TypeWriterController.fromValue(
  TypeWriterValue([
    'First Paragraph',
    'Next Paragraph',
    'Last Paragraph',
  ]),
  duration: const Duration(milliseconds: 50),
);

// you can also integrate the controller with Stream<String> like this one.

final streamController = TypeWriterController.fromStream(
  StreamController<String>().stream
);

TypeWriter(
  controller: controller, // valueController // streamController
  builder: (context, value) {
    return Text(
      value.text,
      maxLines: 2,
      minFontSize: 2.0,
    );
  }
);
